android - 没有注入(inject)注册。您必须将其显式添加到您的模块之一的 'injects' 选项中

标签 android dagger mortar

嗨，我是 dagger 的新手，正在尝试使用简单的 android 应用程序来研究它。

即使有注入(inject)此 View 的模块，我也会从标题中得到错误。谁能帮我弄清楚为什么它不注入(inject) View ？

这是我的应用程序主要模块:

@dagger.Module(injects = {App.class, MainActivity.class}, complete = false)
public class AppModule {
    private final App app;
    public AppModule(App app) { this.app = app; }
    @Provides @Singleton public App provideApp() { return app; }
}

注入(inject)我的 View 的另一个模块:

@Layout(R.layout.sidemenu)
public class SidemenuScreen implements Blueprint{
    @Override public String getMortarScopeName() { return getClass().getName(); }
    @Override public Object getDaggerModule() { return new Module();}

    @dagger.Module(injects= SidemenuView.class, addsTo = AppModule.class)
    public static class Module { 
       public Module() {}
    }

    @Singleton public static class Presenter extends ViewPresenter<SidemenuView> {
        @Inject Presenter() {}
        @Override protected void onLoad(Bundle savedInstanceState) {super.onLoad(savedInstanceState); }
        @Override protected void onSave(Bundle outState) { super.onSave(outState); }
    }
}

如您所见，SidemenuScreen.Module 注入(inject) SidemenuView 并添加到 AppModule。我错了吗？

ObjectGraph 是在我的 Application 类的 onCreate() 方法中创建的:

    ObjectGraph objectGraph = ObjectGraph.create(new AppModule(this));
    objectGraph.inject(this);
    rootScope = Mortar.createRootScope(BuildConfig.DEBUG, objectGraph);

应该注入(inject)的 View 

public class SidemenuView extends LinearLayout {
    @Inject SidemenuScreen.Presenter presenter;

    public SidemenuView(Context context) {this(context, null); }
    public SidemenuView(Context context, AttributeSet attrs) { this(context, attrs, 0); }
    public SidemenuView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        Mortar.inject(context, this);
    }
}

以及使用所有这些东西的 Activity :

public class MainActivity extends Activity {
    private MortarActivityScope activityScope;
    @Inject App app;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        Blueprint screen = getScreenFromIntent(getIntent());

        if (screen != null) {
            MortarScope parentScope = Mortar.getScope(getApplication());
            activityScope = Mortar.requireActivityScope(parentScope, screen);
            activityScope.onCreate(savedInstanceState);

            Mortar.inject(this, this);
        }

        SlidingMenu menu = new SlidingMenu(this);
        menu.attachToActivity(this, SlidingMenu.SLIDING_WINDOW);
        menu.setMenu(R.layout.sidemenu);
    }
}

这里使用了this滑动菜单库:

因此，当调用 menu.setMenu(R.layout.sidemenu); 时，它会膨胀 View 并且 Mortar.inject(context, this); 从 调用>SidemenuView 发生错误的构造函数。

这里是后台:

最佳答案

因此，我从子模块中删除了 addsTo，将 complite=false, library=true 添加到子模块，并在 AppModule 中添加了 includes 现在可以了。但我仍然不明白为什么它不像我以前那样工作。这样做的方式有点不方便，因为每次我实现新模块时，我都需要转到 AppModule 并将此模块添加到包含的模块列表中。它打破了开放/封闭原则，所以我仍然对是否有一种方法可以使用 addsTo=AppModule.class 添加新模块感兴趣。

有什么建议吗？ 谢谢。
